User terminal and radio communication method

Abstract

In order to control a beam failure recovery procedure properly, a user terminal according to one aspect of the present disclosure has a transmitting section that transmits a beam failure recovery request, a receiving section that receives a response signal to the beam failure recovery request, and a control section that controls at least one of whether or not to receive a control resource set and a type of a control resource set to receive, in at least one of a first period from transmission of the beam failure recovery request to start of monitoring for the response signal, a second period from the start of monitoring for the response signal to receipt of the response signal, and a third period from the receipt of the response signal to when reconfiguration is performed.

1 . A user terminal comprising:
 a transmitting section that transmits a beam failure recovery request;   a receiving section that receives a response signal to the beam failure recovery request; and   a control section that controls at least one of whether or not to receive a control resource set and a type of a control resource set to receive, in at least one of a first period from transmission of the beam failure recovery request to start of monitoring for the response signal, a second period from the start of monitoring for the response signal to receipt of the response signal, and a third period from the receipt of the response signal to when reconfiguration is performed.   
     
     
         2 . The user terminal according to  claim 1 , wherein the control section controls so that downlink control channels corresponding to part or all of types of control resource sets are not received during the first period. 
     
     
         3 . The user terminal according to  claim 1 , wherein the control section controls so that a downlink control channel corresponding to at least a control resource set that is used to transmit the response signal is received during the second period and/or the third period. 
     
     
         4 . The user terminal according to  claim 1 , wherein the control section controls so that a downlink control channel that corresponds to a control resource set other than a control resource set that is used to transmit the response signal by using a new beam candidate is received during the second period and/or the third period. 
     
     
         5 . The user terminal according to  claim 1 , wherein the control section controls so that a downlink control channel corresponding to a control resource set that is used to transmit the response signal is not received during the third period. 
     
     
         6 . A radio communication method comprising, in a user terminal, the steps of:
 transmitting a beam failure recovery request;   receiving a response signal to the beam failure recovery request; and   controlling at least one of whether or not to receive a control resource set and a type of a control resource set to receive, in at least one of a first period from transmission of the beam failure recovery request to start of monitoring for the response signal, a second period from the start of monitoring for the response signal to receipt of the response signal, and a third period from the receipt of the response signal to when reconfiguration is performed.   
     
     
         7 . The user terminal according to  claim 2 , wherein the control section controls so that a downlink control channel corresponding to at least a control resource set that is used to transmit the response signal is received during the second period and/or the third period. 
     
     
         8 . The user terminal according to  claim 2 , wherein the control section controls so that a downlink control channel that corresponds to a control resource set other than a control resource set that is used to transmit the response signal by using a new beam candidate is received during the second period and/or the third period. 
     
     
         9 . The user terminal according to  claim 3 , wherein the control section controls so that a downlink control channel that corresponds to a control resource set other than a control resource set that is used to transmit the response signal by using a new beam candidate is received during the second period and/or the third period. 
     
     
         10 . The user terminal according to  claim 2 , wherein the control section controls so that a downlink control channel corresponding to a control resource set that is used to transmit the response signal is not received during the third period.
